  • Minimally Invasive Method for Urethral Catheter Cleaning Suggested at ITMO

    A team of researchers from ITMO, Chelyabinsk State University, and Southern Federal University have suggested a new minimally invasive and safe method for the cleaning of urethral catheters. The new approach involves soft magnetic robots that are nearly 100% effective at removing bacteria-containing biofilm from medical devices. Controlled remotely by a magnetic field, the robots will help prevent the spread of infections, reducing the need for frequent catheter replacement, which is a painful procedure. The new method was described in an article published in ACS Nano.


  • ITMO Fellow Tamer Abdelrazik on Novel Antimicrobial Polymers

    In 2022, the World Health Organization (WHO) described antimicrobial resistance as one of the top ten global health threats currently faced by humanity. Some bacteria, Escherichia coli or Staphylococcus aureus, can spread a variety of infections, which are typically treated with antibiotics, yet over time they can develop resistance to the drugs, thus complicating the treatment and increasing the risk of further spreading. This problem is being addressed by Tamer Abdelrazik, a scientist from the City of Scientific Research and Technological Applications (SRTA-City) who worked at ITMO as part of the ITMO Fellowship program.


  • Farewell to Cavities: ITMO Scientists Develop Toothpaste to Beat Plaque More Efficiently

    Researchers from ITMO’s ChemBio Cluster have developed a mechano-bactericidal toothpaste based on calcium carbonate. Tests have demonstrated that it is two times more efficient than conventional antiseptic toothpastes in removing the bacterial dental plaque that is often at the root of many oral diseases, including cavities. 


  • ITMO Scientists Develop Tool to Boost Vaccine Effectiveness

    Researchers from ITMO University have developed a method for detection and analysis of alterations in bacterial genomes. It will allow researchers to detect new mechanisms of adaptation of bacteria to various environments, including those that increase virulence and resistance to antibiotics. In the future, this method may be used to obtain new data that will help create vaccines with higher efficacy.


  • Picture of the Week: Dendritic Growth of Salt Crystals

    Such structures are used for growing cell cultures. They provide an environment for the growth of metal ions and adjust the media’s acid-alkaline balance.


  • Science-Pop for All Ages: ITMO Scientists’ How-To

    Bioinformatics specialists from ITMO University and the Institute of Gene Biology of the Russian Academy of Sciences have recently published a children’s book about germs. In this interview with ITMO.NEWS, Alexander Tyakht and Dmitriy Alekseev from ITMO’s laboratory ‘Computer technologies’ share about their book and the importance of explaining complex scientific concepts to kids.


  • Microbial Fuel Cell, Space Station, and Electronic Guide: Finals of Quantoriada Competition

    The final round of the Quantoriada international engineering competition for school children has recently kicked off in St. Petersburg’s Planetarium. It’s up to participants to decide what kind of device they want to develop; this year, they could choose between a space station, a drawing robot, an electronic guide, a microbial fuel cell, and other valuable devices. ITMO University’s SCAMT Laboratory has provided a platform for the competition. In this interview with ITMO.NEWS, the participants share their thoughts about the contest and the importance of the devices they’re currently working on.


  • Russian Developers Created a Platform for Interactive Analysis of Metagenomic Data

    A team of developers from Skolkovo, ITMO University and MIPT presented an online service called Knomics-Biota, which allows for a comprehensive study of intestinal microbiome genetic data. Using this service, you can figure out what types of bacteria are present in hundreds of gut metagenomes, their relative proportion, and the amount of vitamins and other beneficial substances they produce. With the help of an interactive interface, you can look at the results from different perspectives, which helps to identify the relationship between microbiota and nutrition, lifestyle and health. The research was published in BioData Mining.


  • At Peace With My Bacteria: How to Achieve a Truly Healthy Lifestyle

    According to the World Health Organization, health is a positive state of physical, mental and social well-being and absence of disease. Nutritionist and somnologist Marina Kogay always tells her patients that eating good food and sleeping well is the way to be healthy and live happily. Ms. Kogay recently gave a public lecture at ITMO University on dieting, weight loss, microbiota and the link between sleep and depression.


  • ITMO Scientists Develop Gene Analysis Software to Combat Superbug Viruses

    Researchers from ITMO University and the Center of Physical and Chemical Medicine have developed an algorithm capable of tracking the spread of antibiotic resistance genes in gut microbiota DNA and revealed additional evidence of resistance gene transfer between different bacterial species. The method can not only contribute to the development of effective therapy schemes, but also curb the spread of superbugs. The results of the research were published in Bioinformatics journal.
